Major (Ionian)
Formula 0 · 2 · 4 · 5 · 7 · 9 · 11 semitones from the root
- Character
- Bright, stable, the reference point for every other scale.
- Works over
- maj7, maj6, maj9
- Why it matters
- Every other scale is described as an alteration of this one. Fluency in all twelve keys is the baseline for reading, transposing and hearing function.
- Written pitch on your horn
- B C♯ D♯ E F♯ G♯ A♯
Practice notes
Why am I practising this?expand
- What it teaches
- The sound and fingering of the major (ionian) in every key, connected by circle of fourths.
- Problem it solves
- Scale knowledge that only exists in three or four keys collapses the moment the tune modulates.
- Physical skill
- Even finger motion across the break, consistent air, matched tone from bottom to top of the range.
- Theory reinforced
- Every other scale is described as an alteration of this one. Fluency in all twelve keys is the baseline for reading, transposing and hearing function.
- Improvisation
- A scale is raw material. Practising it through a cycle means the material is available wherever the harmony goes.
- Ear training
- Sing the root before each new key, then play. If the root you sing is wrong, slow down.
- Common mistakes
- Rushing the awkward keys; letting tone collapse in the low register; playing two octaves in easy keys and one in hard ones.
- Recommended tempo
- Start where it is perfectly clean — often 60-72 BPM in eighth notes — and add 4 BPM only after two clean repetitions.
- Increasing difficulty
- Two octaves, then in thirds, then apply a pattern from the Pattern Lab, then articulate two slurred and two tongued.
- Mastered when
- Every key at the same tempo, same tone and same articulation, with no hesitation between keys.
How to practise it
- 01Set the key movement to fourths and start on a key you avoid.
- 02Play one octave ascending and descending, listening for evenness rather than speed.
- 03Move to the next key without stopping the metronome.
- 04Complete the full cycle back to your starting key.
- 05Log the session and mark whether the whole cycle was clean.
